Application and September 9, 1911. Serial No. 648,553.

This invention relates to box covering,

machines, and has particular reference to a box banding or stripping machine provided with improved apparatus adapted to turn in and press to a box the edges of a strip of.

paper, or the like. Heretofore in banding machines of this character the band or strip is glued to the sides and ends of the box-to extend its edges beyond the top and bottom edges of the box. A form of machine heretofore devised is provided with a table receiving the box coming from the banding device, and in which the edges of the band are turned in and pressed over the top edge and against the bottom of the box by four pairs of rollers arranged on slides opposite to the four sides of the table. These rollers are adapted to be advanced and retired manually by lever mechanism, and in sets, and when advanced, the upper roller of each pair passes above the lower roller which is.

below the box. The upper rollerof each set is adapted to roll down over the top edge of the box under the action of a spring and cam, or springs alone, and so turns down and presses the top edge of the band upon one side of the box while the lower roller presses under the bottom of the box and turns in and presses the band to the bottom of the box.

An object of this invention is to improve.

the construction of .such a paratus, and to effect this, means are provi ed for rendering ing-in rollers and their supporting slides from a single cam, and to provide an automatic ejecting means for the finished box.

According to this invention the pairs of rollers are supported on slides moving in guides carried by a frame and arranged in the form of a cross. These slides are moved into and out of operative positions at the desired moments by meansof acam, provision being made for; adapting the rollers to suit boxes of varying lengths, and widths. The box is held in an expanding frame, arranged, when the '.-machine is. at rest, to be open to a size considerably larger than the box to be operated upon, so that the banded box may be dropped into position without interference with the projecting edges. of the band. When the machine is operated the frame closes in upon the box and holds it firmly, adjustable stops'being providedto prevent crushing of the box. This expanding frame is conveniently operated by means of the cam controlling the movements of the roller slides. When the coverin of the box is completed, the box holding rame is opened and the ejecting mechanism is automatically brought into action and ejects the finished box. 7

For a more complete understanding of the invention, reference is to behad to the following detail description, and the accompanying drawings, in which:

Fig. 5 is a view of the same, similar to Fig. 3. Fig. 4. is a view similar to Fig. 4 disclosing, the structure of Fig. 1. Fig. 4 is a plan view of the same.

- In the drawings, in which like numerals designate. similar parts throughout the several figures, and referring first to- Fig. 1, the turning-in mechanism generally comprises a plurality of pairs of upper and lower turning-in tools 10 and 11, normally spaced away from a central box supporting means in the form of a table 12, and means for moving these turning-in tools 10 and 11 into and out of operative positions with respect to the supporting table 12. The turning-in tools shown are in the form of rollers, and the means for moving them is adapted to reciprocate them in substantially horizontal planes toward and from the sides of the table 12, the latter being also horizontal. The action of the lower rollers 11 is to turn the bottom edges of a covering applied to the sides of a box (see Figs. 1, 5, 6 and 7) to the bottom of the box, while the function of the upper turning-in rollers 10 is to turn the upper edges of the covering over the upper edges of the box and down within the box against the inner side walls, the edges being in each case held in turnedin position by means of suitable adhesive, which is applied to the covering usually prior to the application of the covering to the box. In order to support the side walls of the box against buckling or bending under the strains imposed during the operation of the turning-in tools, a supporting frame 13 is used being adapted to be placed with its sides against the walls of the box during the time that the covering is being turned in (see Figs.4 and 5). In prior machines of this description the supporting frame 13 is in the form of a continuous band of metal or other material adapted to be placed by hand around the box being operated upon, and the turning-in tools are arranged for manual operation.

My invention contemplates making the various operative parts of the machine adjustable to suit any size of box within given limits; the automatic operation of such parts, and in addition contemplates certain improvements in the turning-in devices and their associated mechanisms, the machine being reorganized with its elements forming new combinations to the securement of a far greater eflicienc 1 1 is the main supporting frame of the machine of my invention. The main body of the frame 14 lies in a horizontal plane and is supported by legs 14 The machine shown is adapted for operation upon rectangular boxes and to this end is provided with four ways 15v at right angles to each other, radiating from a central box support or table 12 aforementioned. On each of these ways is a slidable and adjustable bracket shaped carrier member 16. This member carries the upper and lower turning-in tools 10 and 11 and the elements of the supporting frame 13. The carrier members are angle shaped, one branch being arranged to adjustably slide up and down on this upper arm of the carrier member 16 and to be held in adjusted position by a set screw 18 passing through it and engaging a clampmg shoe 19 on the back of the carrier arm. At the upper end of the supporting member 17 is fixed'transver'sely a shaft 20, the shaft being journaled in spaced ears 21, Fig. 2, formed on the supporting member and being held in its journals by a collar 22 on the shaft, the collar being provided with a set screw 23 for fixing it to the shaft. Adjustably mounted on each end of each shaft is a pair of supporting arms 24, the inner ends of each pair of supporting arms carrying one of the upper turning-in tools 10, of which there are four in the complete machine, as shown. The outer ends are bored to receive the shaft 20,- and are split to the bore as shown, and clamping screws 25 are provided extending transversely of the slits for the purpose of securing the arms in an adjusted positions on the transverse sha t .20. -Thus it is evident that a turning-in tool in the form of a roller 10, of any desired length to suit the size of the box to be covered may be supported between each pair of arms 24, it being only necessary to spread or contract the arms laterally on the shaft 20 to accommodatethe roller desired. The collar 22 aforementioned is provided with an inwardly extending arm 26 which is normally pulled downwardly by means of a splral spring 27 the upper turning-in roller 10 belng thus normally urged downwardly by the shaft 20 and the supporting arms 2 1 at all times.

Normally, the turning-in tools 10 rest upon the upper sidesof the frame members 13, as shown in Fig. 1. The frame members '13 are made in sections, one section corresponding to each turning-in tool and being, like the turning-tools, arranged in accordance with the size of the box to be operated upon. The sections of the supporting frame 13 are removably attached one to each carrier member 16. Two spaced rods 28 1pass through-the body of the carrier, as s own in Fig. 1, being joined at their outer ends by a bar 29 and at their inner ends by a bar 30. The rods are forced inwardly by springs 31 surrounding them and which hear at one end against the carrier 17 as shown in Fig. 1, the other end against the bar 30. The bar 30 is gained on its inner edge, as shown in detail in Fig. 8, and supports a section of the frame 13 on the gained portion, the section being correspondingly gained and removably held in position by means of a clamping plate 32 and screw 33. Thus a section of any desired dimension may be placed in position. Although normally urged inwar ly, inward movement of the sections of the frame is limited in each case by a pair of bracket shaped stops 34 adj ustably mounted on the frame 14 one on each side of the carrier and positioned to engage the laterally extended ends of the bar 29.

On the lower branch of each carrier 16 is supported one of the lower turning-in rollers 11, of which there are'four such rollers. There is provided a transversely fixed way in the form of a bar 35 at the inner end of each lower branch. Laterally adjustable arms 36, which slidably embrace the bar 35 at their inner ends and which may be secured in adjusted position by a set screw 37, support at'their inner ends the lower turning-in rollers 11. Thus it will be seen that by moving the adjustable arms 36 laterally, a turning-in roller of any desired dimension to suit the size box being covered may be placed in position and supported by the arms 36. The adjacent bars or ways 35 are placed in different planes as shown in Fig. 1, whereby irrespective of the length of the 7 bars, they may be moved one over the other,

as the carriers are-moved and without interference.

All of the operating devices aforementioned are adapted to be moved by a common operating mechanism. A single cam is centrally disposed beneath the supporting table, this cam being numbered 39 in Fig. 1. This cam is disposed in a horizontal plane and supported upon a sleeve shaft 41 journaled in bearing 42 in the frame 14. It is adapt ed to be rotated by means of beveled gears 43, 44, on the sleeve 41, and by a shaft 45, respectively, the shaft 45 bein journaled transversely of the frame 14 be ow the top 14 in bearings 46 and 47. At right angles to the shaft 45 is a power shaft 57 adapted to rot-ate the shaft 45 one revolution at a time through a one revolution clutch 48 of any well known type, this clutch being shown conventionally. As is well known a one revolution clutch is adapted to rotate a given part one revolution and then stop the rotation automatically.

In the upper face of the cam 39 is formed a cam groove'49 of the shape clearly shown in dotted lines'in Fig. 2 and more clearly in Fig. 3. A cam roller 50 attached to each slide on which the carrier member 16 is adjustable, engages in this groove. By an inspection of the shape of the groove it will be seen that upon rotation of the cam 39 with its groove 49, the alternate carriers with their operating devices, including the turning-in tools and so forth, may be moved simultaneously inward to operating position while the intermediate carriers are held stationary after having advanced till the sup porting frames 13 touch the box, and then It willbe observed further that these revolution clutch 48 the cam 39 is moved exactly one half revolution and then stopped.

With this understanding of the principal mechanisms of the machine and the means for operating them automatically, the operation of the several operating devices upon a box to be covered, will be readily observed from a consideration of Figs. 1, 4 and 5. In Fig. l a box 51 is shown in dotted lines supported bottom down upon the operating table 12, with the edges of an applied cover 52 projecting downwardly and upwardly from the sides of the box (see also Fig. 8). It is desired that these edges be turned in over the upper edges of the box and glued tom of the box, the sections of the supporting frame 13 on each side of the box have at the same time been moved up into engagement with the vertical walls of the box, this movement, and the consequent pressure of the sections upon the box, as defined by the springs 28, is limited by the'stops 34 previously adjusted. It is to be observed that all of the sections contact with the bevel cam groove 49, this groove being so shaped as to move all of the sections of the frame up to the box, although only the alternate turning-in devices are moved to operating positions. This is accomplished by giving to the intermediate carriers a lesser degree of movement than is given to the alternate carriers which are moved all the way up into operating positions. Just after the engagements, of the sections '13 with the sides of the box, the upper turning-in rollers 10 engage the upper edges of the box covering, turn the same in over the upper edges of the ends of the box and then down and apply the same to the insides of the ends of the box, the rollers 10 being drawn suddenly but firmly downwardly just as soon as their center lines are projected beyond the edges of the box. The sliding supporting member 17 having been previously adjusted to bring the top of the supporting frame flush with the top of a box to be operated upon, there is no interference through the projection of the upper edge of the box through the frame, and a smooth and firm operation results. 'Immediately these operations have been performed,the alternate carriers, shown in Fig. 1, are carried outwardly again to normal position by the cam, the upper turning-in rollers by virtue of the pivot of their supporting arms being higher than the-t0p of the box being operated upon, simply rolling upwardly and away from the box, and both lower and upper turning-in rollers pressing the edges of the covering by a firm rolling act-ion as they recede. These rollers shown in Fig. 1 having taken their normal position, the intermediate rollers shown at right angles to them in.Fig.-2, are moved by the cam into operative position together with. the supporting frame 13 as an entirety, and in a manner entirely similar to that described in connection with the opposite pairs of rollers 10 and 11 shown in Fig. 1.

In connection with the machine as thus described, I provide means for automatically ejecting the finished product. To this end I make the table 12 movable vertically by supporting it on the upper end of a vertically reoiprocable rod 54 which passes cen-' trally through the bearing sleeve 41 which carries the cam 39. On the lower end of this rod I secure a cross head 55 by which the rod may be reciprocated, the cross head being guided by rods 56 oneach side of the rod 54 and fixed to the member 57 attached to the frame. To one side. of the frame 14" below its top is a bracket 58 to which is pivoted a three armed lever 59, the central arm of which is connected by a pin and slot connection 60 with the rod 54. The lower arm 61 of this lever 59 is connected by the rod 62 to a disk 63 on a transverse shaft 64,

the shaft terminating in the disk, so that the disk 63 may be rotated with the rod 62 without interferences from the shaft. This transverse shaft is geared to the upper shaft 57 through a one revolution clutch 65 (see Fig. 3) of any well known type. An operating member 66, (Fig. 1), for this clutch is provided, and its outer end 67, see Fig. 1, is extended upwardly into the path of movement of a lug 68 on a disk 69 on the shaft 45, the lug being beveled, as shown, to move the operating lever 66, laterally by means of its engagement with a pin 70, once each time the shaft 45 is operated. By adjusting the disk 69 upon the shaft, this operation of the one revolution clutch is timed to take place immediately after the edges of the box coverin have been completely turned in and all of the operating devices have receded mounted to slide in the bearings 74 on the extension bracket 75 secured to the upper end of one of the carriers 16. The motor mechanism comprises an oscillatory rod 7 6, adapted to be moved inwardly toward the table by a spring 77 connected at one end to the rod 7 6, and at the other end to the upperend of the lever 78 pivoted at 79 intermediate its ends and connected at its lower end by link 80 to the arm 71. The shaft 79 is fixed in position, the lever being loosely journaled upon it. On one end the shaft 79 carries an adjustable collar 81 provided with a notch and shoulder 82. A latch member 83 pivoted at' one end to the rod 76 is adapted to engage at its opposite end in this notch 82 when the rod 76 has been moved outwardly. When the rod is moved outwardly tension is thereby placed upon the spring 77. An actuating member 84, pivoted at one end to the rod 76 and engaged at its opposite end in notch 85 by pin 86 on the upper end of the lever7 8, is adapted to move the rod 7 6'outward1y when the lever 78 has its lower end moved inwardly. -An outward lateral extension 87 extending from the lever 78 carries an adjustable abutment screw 88 adapted to engage the underside of the latch 83 and raise the same from the notch 82.

When the turning-in of the back cover is completed, and just before the disk 69 stops, the operating lever 66 is moved aside by the lug 68 to let the clutch 65 into operative position. The disk 63 now makes one complete revolution drawing the rod 62 backwardly and swinging the oscillating lever 59, whereupon the arm 71 moves the lever 78 outwardly, elongates the spring 77 to exert a tension on rod 76, and finally brings the abutment 68 against the latch 83 releasing the same and admitting of the snapping of the pivoted rod 76 inwardly under the tension of the spring 77. The plunger 73 is, therefore, shot inwardly through the bearings 74. The swinging of the lever 59 raises the plunger rod 54 carrying the table 12 therewith above the turning-in devices, and the projection 87 carrying the abutment 88 is disposed at such an angle to the lever 78 that the abutment 88 does not strike the latch 83 until the box 51 upon the table 12 is carried upwardly opposite to the pusher rod 73, the latter being spring 77 is normally inactive but under 1 slight tension which is increased upon the outward movement of the lever 78.

It is very desirable that the operating devices for turning-in the box covering be not started upon a second operating cycle until the ejecting mechanism has been returned to normal position. To prevent this I provide a latch operable by the ejecting mechanism which prevents actuation of onerevolution of the clutch 48 of the operating device until the ejecting mechanism has completed:

This latch is in the form itsv operations. of a pivoted angle lever 89 pivoted at 90 to the frame, and engaging at one end, by

means of an anti-friction roller 91, the periphery of the disk 63, and at the other end the operating lever 53 for the clutch 48 as; shown in Figs. 1 and'3. The periphery of; the disk 63 is notched, as shown, in Fig. 1, at one point only to receive the roller 91 on the end of the lever 89. The upper end of the lever is provided with a projecting portion 92 which may be projected over the top of the operating lever 53 and prevent its being raised from the clutch 48 when the ejecting mechanism is in the course of operation. The disk 63 holds the projection 92 over the lever 53 and does not remove it until the cycle is completed and the disk having made one complete revolution the roller 91 again rests in the notch in the disk.

The above described form of my invention I find very efficient, but in its use in some instances, there has arisen certain trouble due to the sticking of the rollers 10 and 11 to the turned in portions 52 of the wrapper.

Some times the needless excess of adhesive is pressed from the wrapper and is taken up by the covering rollers 10 and 11, and upon the outside of the portions of covering material 52, and the rollers having turned the portions 52 into contact with. the box, will, on the return movement, stick to the previously turned-in portion, and wrinkle, tear or removethe same. Therefore, I have provided means for moving the rollers away from. the turned-in portions prior to their removal from within the box on the return movement. This is embodied in the preferred form of my invention: This form is clearly shown in Fig. 1, which is a view similar to Fig. 1, Fig. 3 which is a view similar to Fig. 3, Fig. 4 similar to Fig. 4, and Fig. 4 which is a plan View the portion of the machine j shown in Fig. 4. Referring now to these figures of the drawings, it will be noted that all the parts, like those of the machine previously described, are designated by like.

numerals. Instead of the rod 20 each support 17 carries a transversely ex'tending bar 93 upon which are slidably mounted two supporting arms 94. The upper rollers 10 are carried by brackets 95 of U-shape, as

shown, pivoted at one end to the arms 94. The arms 94 are provided with upward extension 96 which support transversev rods 97. At opposite ends, these rods carry inwardly extending operating levers 98 connected by means of links 99 with the U- s'haped brackets 95 carrying the rollers.

The levers 98 are rigidly connected with the rods 97, which rods are journaled to turn in the projections 96. Also rigidly, connected with each of the rods 97 is a rearwardly extending operating lever 100 which projects from the rods 97 at such a point as to clear the mechanism below them. The levers 100 are each connected at their outer ends to a link 101 extending downwardly through the table 14 of the machine and connecting the cam levers 102 pivoted to the extensions 1% of the bracket 46. The cam levers are provided with rollers 104 which are engaged by a ring cam member 105 supported from the cam wheel 39. (See Figs. 1 and 3 The cam 105 is so shaped on its under face as to depress the cam levers 102 immediately after the turning in rollers have reached their extreme inner position, as shown in full lines in Fig. 4 and to raise the turning-in rollers immediately to the dotted line position shown in Fig. 4, whereby the rollers are given return movement by the mechanisms. previously described and moved without the range of the box. This mechanism has to do in this embodiment only with the upper turning-in rollers 10. For securing the. right movement of the lower turning-in rollers 11 a different mechanism is used. 'The lower turning-in rollers 11 are carried between the links 106 on the ends of the inwardly extending arms 107, which are slidably mounted on a transversely extending bar 108, where-by adjustment of the arms 107 to'said various lengths of rollers may be had'in the same manner as the construct-ion of mechanism previously ressin the band to the underside of the ox strike the table 12, and movement of the frame carrying them continues inwardly, thus inc ining the roller frames to the position shown in'Fig. 4' whereupon the extension 112 of the latch 110 engages the return bar 108 and holds the frame. Thus the lower turning-in rollers are held away from the underside ofthe box after the turning-in operation on the bottom s completed and aremaintamed in this position during the return movement. Adjustable releasing stops 113 are' provlded on the frame of the machine, and the rear ends of the latches 110 are beveled as at 111 to engage these stops at the end of the outward movement of the lower rollers, whereby the latch is lifted, and the springs 109 return.

the rollers to the normal position shown in Fig. 1. Thus a most efiicient turning-in action is had free from the troubles due to sticking of the rollers to the turned-in portions of wrappers. It willbe noted that in this embodiment the sections of the frame 13 (see Fi 1 are pressed inwardly by springs 114 o the extension type, which extend between projections115 on the member 17, and 116 on the ends of the rods 28 which carry the sections 13. Collars 34 are fixed upon the rods 28 and engage against the brackets 17. to limit the inward move ment of the rods.

In Figs. 8 and 9 I show a still further modification of m invention. This modification is very similar to that shown in Figs. 1, 4 and 4". The essential diiference is that the rollers 10 are not automatically moved away from the turned-in portions of the wrapper when the turning-in operation has been completed. To this end the connections 96 to 104, shown in Figs. 4 and 4 are omitted from the upper turning-in rollers, and the lower turning-in roller 11 is rigidly mounted on the member 36, similarly to the turning-in rollers of the form of'Fig.

1. The upper turning-in rollers are carried by the claws 95' pivoted on the ends of the arms 94, slidably mounted on cross bars 93 similarly to the rollers 11 of the form of Figs. 1 and 4", previously described. As in a machine of this form, the sections 13 of the frame are carried by rods 28 which are pressed inwardl by means of springs 114. As is the case with the form of Figs. 1, 2, 3, etc, this frame is limited in its inward movement by means of the upright stops 34 which are adjustable along the bed of the frame.

main sectionlO by means of a shaft 10 which passes axially through it, the supporting arm 24 being provided .with an engaging shoulder as shown. Another section similar to 10 is, of course, provided on the opposite end of the main section 10*.
